|Location and accuracy||This occurrence is at an elevation of 3,500 feet about 1.4 miles west of Parsons Peak in a saddle at the head of Burro Creek. It is in the south-central part of section 36, T. 27 S., R. 58 E. of the Copper River Meridian. It is shown as mineral occurrence 8 by Redman and others (1984) and as number S066 by Wells and others (1986).|
Geologic descriptionAccording to Redman and others (1984), this occurrence consists of quartz vein float from the Burro Creek fault zone where it cuts biotite quartz monzonite of the Ferebee pluton at the head of Burro Creek. The quartz-vein float contains pyrite and chalcopyrite A sample contained 1,580 ppm copper, 50.5 ppm silver, 170 ppm lead, and 128 ppm molybdenum. The veins were found only as float along the fault trace. The mineralization must be younger than the Late Cretaceous to early Paleocene Ferebee pluton (Redman and others, 1984).
